Question 581
If the radius of a rotating ring is doubled while keeping mass and angular speed constant, what happens to its kinetic energy?
Question 582
What is the angular acceleration of a body with I = 0.5 kg m² when τ = 2 Nm is applied?
Question 583
A body gains 36 J of kinetic energy after a torque acts on it. If no energy is lost, what is the work done by the torque?
Question 584
What is the work done by a constant torque of 6 Nm in rotating a body through 4 radians?
Question 585
